Description
The H-50D is a high-performance, environmentally sealed diaphragm regulator specifically designed for challenging conditions. Diaphragm first stages are a trusted choice among cold-water divers, and the H-50D is engineered to deliver reliable performance in the harshest settings. Its balanced, dry chamber diaphragm prevents water intrusion, ensuring smooth and consistent airflow at varying depths and tank pressures—even in freezing temperatures.
Equipped with two opposing high-pressure ports, the H-50D offers flexible SPG placement and accessory compatibility, allowing for personalized hose configurations. Four stationary low-pressure ports, including high-flow options, enhance air delivery—providing up to 15% more airflow than standard LP ports.
Features:
- Balanced, sealed diaphragm
- Dry balance chamber
- Two HP ports, four LP ports
